PF87 Nano-Reinforcing Material: A High Reinforcement White Rubber Filler Derived from Kaolin for Superior Performance

In the global industrial wave pursuing high performance and sustainable development, rubber material technology is at a critical turning point. Traditional reinforcing fillers such as carbon black and precipitated silica, while excellent in performance, have limitations in terms of color, processability, cost, or environmental friendliness. This has driven the demand for a high reinforcement white rubber filler that can overcome these challenges. Leveraging its profound material science and technological innovation capabilities, SaneZen Group has introduced a disruptive product — PF87 Functional Nano-Reinforcing Material. As a leading rubber filler manufacturer China, we have developed PF87, a kaolin based nano filler for rubber that achieves comprehensive performance transcendence through cutting-edge nanotechnology and surface engineering, providing a white reinforcing solution that combines high performance, environmental friendliness, and exceptional cost-effectiveness for industries including tires, sealing products, vibration damping components, hoses, shoe soles, and even wires and cables.

I. Market Pain Points: The Performance “Ceiling” of Traditional Fillers and How PF87 Breaks Through

The traditional filler family each has its constraints:

  • Carbon Black: Excellent reinforcing effect, but its black color restricts its use in light-colored products. High loading often poses processing challenges and equipment wear, creating demand to replace carbon black in colored rubber products.
  • Precipitated Silica: Primarily used in “green tires” to reduce rolling resistance, but it is costly, hygroscopic, difficult to disperse, and selective towards curing systems. This drives the search for a cost effective alternative to silica in tires.
  • Traditional Kaolin: Low cost and high whiteness, but particle sizes are mostly in the micron range, offering limited reinforcement, mainly serving as a filler and extender, unable to improve tensile strength in light colored rubber effectively.

The market urgently needs a new type of functional filler that can break these limitations, providing high strength and high air-tightness in light-colored or colored products, while also possessing excellent processability and cost advantages. PF87 is born for this purpose, designed to be a low cost high performance filler that enables manufacturers to achieve carbon black reinforcement without color.

II. Decoding Core Technologies: How PF87 Achieves Global Leadership

The success of PF87 is no accident; it is built upon SaneZen Group’s four core technological pillars as a leading Caucho Relleno funcional Fábrica:

This graph presents the laser particle size analysis results for PF87, demonstrating its precisely controlled nano-scale structure. With a D50 of 153nm and D90 of 3.394μm, PF87 achieves a dominant nano-particle distribution while maintaining excellent dispersion stability. This optimized particle morphology is engineered to maximize surface area, enhance polymer-filler interaction, and deliver exceptional reinforcement and air-tightness—making PF87 a reliable choice for high-performance applications such as tire innerliners, sealing systems, and structural rubber components.
  1. Surface Treatment Technology Team: From “Physical Filling” to “Chemical Bonding”
    Through unique surface modification technology, functional organic groups are grafted or coated onto the surface of the nano-platelets. This treatment not only significantly improves the compatibility and bonding force between PF87 and organic polymer matrices (especially non-polar rubbers like EPDM and IIR), solving the industry pain points of difficult dispersion and easy agglomeration of inorganic fillers in rubber, but also allows for customization based on customer needs to optimize performance in different polymer systems.
  2. Application Technology Team: Bridging the Lab and the Production Line
    SaneZen has an experienced application development team with deep expertise in rubber and plastic formulation design and processing technology. They provide not just products, but complete solutions ranging from formulation customization and development, process parameter guidance, to production problem-solving, ensuring PF87’s performance advantages are perfectly reproduced on the production line.
  3. Bio-based and Polymer Technologies: Strategic Reserves for the Future
    Beyond the PF series, SaneZen Group has strategically invested in bio-based filler technology and specialty polymer additive technology, demonstrating the company’s commitment to the long-term development of the industry through a technology-driven strategy, offering customers a continuously innovative product portfolio.

III. Peak Performance: In-Depth Analysis of PF87’s Comprehensive Advantages

Based on the aforementioned core technologies, PF87 demonstrates a series of compelling performance advantages:

  • Exceptional Reinforcement Performance, Rivaling N550 Carbon Black: In an EPDM sulfur curing system, the compound filled with 130 phr of PF87 achieved a modulus at 100% elongation (M100) of 2.55 MPa and a tensile strength of 15.87 MPa. The overall reinforcement effect is close to that of N550 carbon black, breaking the traditional constraint that “high reinforcement requires carbon black.” This makes PF87 a true high modulus mineral filler for structural rubber.
  • Outstanding Air Tightness, Entering the “Forbidden Zone” of Tire Inner liners: Its unique ultra-fine platelet structure can form a dense, tortuous physical barrier network within the compound, effectively slowing gas molecule permeation, making it one of the few mineral fillers globally capable of being applied in high-end fields like tire innerliners. As a specialized white filler for tire inner liner applications, PF87 serves as an excellent high air retention filler for tire compounds.
  • Excellent Processing and Application Performance: High loading with low hardness increase; easy dispersion and good flowability; favorable curing characteristics; effectively suppresses blooming and iridescence.
  • Comprehensive Durability and Stability: Excellent heat aging resistance; improves media resistance and fatigue resistance; high insulation; chemically stable, non-toxic, and odorless.
  • Unbeatable Cost Performance: Compared to internationally benchmarked functionalized kaolin products, PF87 surpasses them in key reinforcement and air-tightness indicators. Meanwhile, leveraging localized raw materials and advanced processes, PF87 offers customers an approximately 20% comprehensive cost advantage, helping reduce raw material cost in rubber formulation and serving as an effective solution to reduce cost in high volume rubber production filler.
